[0002] Desert photovoltaic desertification control is an ecological and economic synergy development model that combines photovoltaic power generation with desert management. Its core is to build photovoltaic power stations in desert areas and use the shading and wind-blocking functions of photovoltaic panels to improve the local microenvironment.

[0003] Current desert photovoltaic sand control systems generally directly replicate traditional sand control models within the photovoltaic field without comprehensively considering the adaptability of traditional models to the photovoltaic field. This has varying degrees of impact on the subsequent management, operation and maintenance, and power generation efficiency of the photovoltaic field. Utility Model Content

[0004] The purpose of this invention is to provide a desert photovoltaic sand control system that can fully integrate the layout characteristics of the photovoltaic field and set up different windbreak and sand-blocking forest belts in a targeted manner, so that the sand control measures are more adaptable to the photovoltaic field.

[0005] To solve the above-mentioned technical problems, the technical solution of this invention is as follows:

[0006] A desert photovoltaic sand control system includes:

[0007] A photovoltaic power plant area was set up in the desert;

[0008] At least one set of booster stations located within the designated photovoltaic field area;

[0009] At least two sets of photovoltaic panels are installed within the designated photovoltaic field area;

[0010] At least one working road must be provided between at least two sets of photovoltaic panels;

[0011] A first windbreak and sand-blocking forest belt is set up around the periphery of the photovoltaic field area;

[0019] Optionally, the second windbreak and sand-blocking forest belt includes:

[0020] The second sand barrier intersects perpendicularly with each other, and the second sand barrier as a whole is a grid-like structure.

[0021] The shrubs are placed within the squares of the second sand barrier, and the shrubs are arranged in a scattered pattern at equal intervals.

[0022] Optionally, the fourth windbreak and sand-blocking forest belt includes:

[0023] The second sand barrier intersects perpendicularly with each other, and the second sand barrier as a whole is a grid-like structure.

[0024] The shrubs are placed within the squares of the second sand barrier, and the shrubs are arranged in two rows in a strip.

[0025] Optionally, the fifth windbreak and sand-blocking forest belt includes:

[0026] The second sand barrier intersects perpendicularly with each other, and the second sand barrier as a whole is a grid-like structure.

[0027] Shrubs placed within the squares of the second sand barrier.

[0028] Optionally, the second sand barrier is a willow sand barrier and / or a straw sand barrier.

[0031] Optionally, the first sand barrier is a sandbag sand barrier.

[0032] Optionally, the sandbag barrier is made of biodegradable material.

[0033] The beneficial effects of this utility model are: it changes the traditional practice of directly replicating the desertification control model to the photovoltaic field, and fully combines the layout characteristics of the photovoltaic field (such as the functions and locations of different areas such as photovoltaic panels, working roads and substations) to set up different windbreak and sand-blocking forest belts in a targeted manner, making the desertification control measures more adaptable to the photovoltaic field.

[0034] By setting up windbreak and sand-blocking forest belts in different areas (such as between the work road and the photovoltaic panel), it is possible to effectively prevent wind and sand from burying the work road, ensure smooth road access, provide convenient conditions for the later management and operation of the photovoltaic field, and reduce the obstacles to operation and maintenance work caused by wind and sand.

[0046] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0047] like Figure 1-8As shown, an embodiment of this utility model proposes a desert photovoltaic sand control system, comprising:

[0048] A photovoltaic power plant area was set up in the desert;

[0049] At least one set of booster stations 6 located within the designated photovoltaic field area;

[0050] At least two sets of photovoltaic panels 1 are installed within the designated photovoltaic field area;

[0051] At least one working road 5 is provided between at least two sets of photovoltaic panels 1;

[0052] A first windbreak and sand-blocking forest belt is set up around the periphery of the photovoltaic field area;

[0053] A second windbreak and sand-blocking forest belt is set up around the periphery of the booster station 6;

[0054] The third windbreak and sand-blocking forest belt is located under the photovoltaic panel 1;

[0055] A fourth windbreak and sand-blocking forest belt is set between adjacent photovoltaic panels 1;

[0056] The fifth windbreak and sand-blocking forest belt is set between the photovoltaic panel 1 and the working road 5.

[0057] In this embodiment, the traditional approach of directly replicating desertification control methods to photovoltaic fields is changed. Instead, different windbreak and sand-blocking forest belts are set up in a targeted manner, taking into full account the layout characteristics of photovoltaic fields (such as the functions and locations of different areas such as photovoltaic panels 1, working roads 5, and booster stations 6), making the desertification control measures more adaptable to photovoltaic fields.

[0058] By setting up windbreak and sand-blocking forest belts in different areas (such as between the work road 5 and the photovoltaic panel 1), it is possible to effectively prevent wind and sand from burying the work road 5, ensure smooth road access, provide convenient conditions for the later management and operation of the photovoltaic field, and reduce the obstacles to operation and maintenance work caused by wind and sand.

[0059] The photovoltaic field area was divided into different functional zones, such as the photovoltaic array sand-fixing zone, the road protection forest zone, the outer windbreak and sand-fixing forest belt zone, and the substation protection forest belt zone. Each zone was equipped with appropriate sand barriers and vegetation, thus achieving zoned management.

[0060] like Figure 1 , 2 As shown, in an optional embodiment of this utility model, the first windbreak and sand-blocking forest belt includes:

[0061] The second sand barrier 4 intersects perpendicularly with each other, and the second sand barrier 4 as a whole is a grid pattern;

[0062] The shrubs 3 are placed in the squares of the second sand barrier 4, and the shrubs 3 are arranged in two rows and one strip.

[0063] Specifically, the width of the first windbreak and sand-fixing forest belt in the designated photovoltaic area along the prevailing wind direction is 50-100 meters, and the width of the first windbreak and sand-fixing forest belt in the designated photovoltaic area along the non-prevailing wind direction is 30-50 meters. No sand-fixing measures are taken on the leeward slope, and when planting on the windward slope, tall sand dunes are planted to two-thirds of their height, with the top of the slope naturally smoothed. The "two rows and one belt" pattern consists of two rows of forest belts (shrubs 3) and one row of natural vegetation restoration belts, arranged alternately.

[0064] The second sand barrier 4 can be a sand willow sand barrier. The shrub 3 can be of the following varieties: Haloxylon ammodendron, Caragana korshinskii, and Calligonum mongolicum. Different varieties of shrub 3 are mixed and interspersed, with a planting density of 2m×2m.

[0065] In this embodiment, by constructing a wide sand-blocking belt around the photovoltaic field, the surrounding wind and sand can be effectively intercepted, reducing the erosion of photovoltaic panels 1, operation roads 5, and substation 6 by wind and sand, reducing the problem of reduced power generation efficiency caused by sand covering photovoltaic panels 1, and ensuring the long-term unobstructed operation and maintenance channels of the field, thus providing an ecological barrier for the safe and stable operation of the photovoltaic field.

[0066] The second sand barrier 4, which uses mutually perpendicular intersecting grid squares, can form a three-dimensional sand-blocking grid on the ground surface, effectively dividing the shifting sand, reducing wind speed, and preventing sand dune movement. The grid is matched with two rows of shrubs 3 arranged in a strip. Through the dual effects of soil fixation by the vegetation roots and physical sand blocking by the sand barrier, a composite sand-fixing system of grid sand fixation and vegetation sand locking is formed, which significantly improves the stability of the sand-fixing structure.

[0067] The two-row, one-belt layout, alternating between two rows of forest belts and one row of natural vegetation restoration belts, not only rapidly constructs sand-blocking barriers through artificially planted shrubs, but also preserves space for natural vegetation restoration, promoting the natural recovery of local plant communities and forming a synergistic effect between artificial intervention and natural restoration; the mixed planting of different shrub species can utilize the ecological complementarity between species to enhance the resilience and ecological diversity of the vegetation community and improve the long-term effectiveness of windbreak and sand fixation.

[0068] Setting up sand-blocking belts 50-100 meters wide in the direction of the most severe wind and 30-50 meters wide in the direction of the non-severe wind, combined with the design of not taking sand-fixing measures on the leeward slope and planting sand-blocking belts at two-thirds of their height on the windward slope and naturally reducing the peak, can precisely target the intensity of wind and sand erosion in different wind directions, maximize sand-blocking efficiency, and reduce resource waste.

[0069] like Figure 3 As shown, in an optional embodiment of this utility model, the second windbreak and sand-blocking forest belt includes:

[0070] The second sand barrier 4 intersects perpendicularly with each other, and the second sand barrier 4 as a whole is a grid pattern;

[0071] The shrubs 3 are placed in the squares of the second sand barrier 4, and the shrubs 3 are scattered at equal intervals.

[0072] Specifically, the second windbreak and sand-blocking forest belt is located within 6 meters of the booster station 6. The second sand barrier 4 has a size of 1m×1m. The shrubs 3 can be of the varieties of Haloxylon ammodendron, Caragana korshinskii, and Calligonum mongolicum. Different varieties of shrubs 3 are mixed and interspersed, with a planting density of 2m×2m.

[0073] In this embodiment, by constructing the windbreak and sand-blocking forest belt around the substation 6, the wind and sand can be effectively blocked from nearby, reducing the coverage and wear of sand and dust on the electrical equipment of the substation 6, reducing the risk of equipment failure, and ensuring the stable operation of the substation 6.

[0074] The second windbreak and sand-blocking forest belt is set within 6 meters around the booster station 6. Combined with the second sand barrier 4 with a 1m×1m grid pattern, it can make full use of the limited space around the booster station 6 to form a compact and effective windbreak and sand-fixing structure. It will not affect the normal operation of the booster station 6, but can also specifically block the surrounding wind and sand and protect the equipment of the booster station 6 from wind and sand erosion.

[0075] The intersecting grid of sand barriers forms a fine mesh on the ground, which can effectively separate shifting sand, reduce wind speed, and prevent small-scale sandstorms. Within the grid, shrubs 3 are scattered at equal intervals. Through the synergistic effect of soil fixation by the vegetation roots and physical sand blocking by the sand barriers, a composite protection system of grid sand blocking and scattered sand fixation is formed around the booster station 6. This strengthens the sand fixation effect in local areas and reduces the impact of sand accumulation on the maintenance and operational safety of the booster station 6 equipment.

[0076] The shrubs 3 are arranged in a scattered pattern at equal intervals, which can evenly cover the sand barrier grid, make full use of the limited space, avoid water competition caused by excessive vegetation density, and adapt to the arid and water-scarce environment of the desert. The mixed and cross-arranged arrangement of different varieties of shrubs 3 utilizes the ecological complementarity between species to enhance the resilience of the vegetation community, improve the long-term effectiveness of windbreak and sand fixation, and the scattered layout facilitates targeted management and replanting in the later stage, reducing the difficulty of management.

[0077] like Figure 4 , 5 As shown, in an optional embodiment of this utility model, the fourth windbreak and sand-blocking forest belt includes:

[0078] The second sand barrier 4 intersects perpendicularly with each other, and the second sand barrier 4 as a whole is a grid pattern;

[0079] The shrubs 3 are placed in the squares of the second sand barrier 4, and the shrubs 3 are arranged in two rows and one strip.

[0080] Specifically, the second sand barrier 4 is a sand willow sand barrier or a straw sand barrier. The shrub 3 can be of the variety Haloxylon ammodendron, with a planting density of 2m×2m.

[0081] In this embodiment, by constructing the windbreak and sand-fixing forest belt between the photovoltaic panels 1, the accumulation of sand and dust on the surface of the photovoltaic panels 1 can be effectively reduced, mitigating the problem of decreased power generation efficiency caused by sand and dust shading. Simultaneously, the sand-fixing measures improve the microenvironment of the site, reduce wind and sand erosion of the photovoltaic equipment, extend the equipment's service life, and achieve synergistic effects between photovoltaic power generation and desertification control, providing a sustainable technical solution for new energy development and ecological restoration in desert areas.

[0082] The fourth windbreak and sand-blocking forest belt is set between adjacent photovoltaic panels 1, using two rows and one strip of shrubs 3, combined with a grid of sand willows or straw barriers, which can closely fit the spatial structure between photovoltaic panels 1. This layout can make full use of the limited area between photovoltaic panels 1, while avoiding adverse effects on the installation, operation and maintenance and power generation efficiency of photovoltaic panels 1, thus achieving an organic integration of sand control measures and photovoltaic field layout.

[0083] The intersecting grid-like sand barriers create a three-dimensional sand-blocking structure between the photovoltaic panels, effectively separating shifting sand, reducing wind speed, and minimizing sand accumulation between the panels. The two rows of saxaul trees, arranged in a strip, utilize the dual effects of root stabilization and physical sand-blocking through the sand barriers to construct a composite system of grid-based sand blocking and vegetation-based sand retention. Simultaneously, the shading effect of the photovoltaic panels combined with the drought-resistant characteristics of the saxaul improves the microenvironment between the panels, promotes vegetation growth, further enhances the sand-fixing effect, and creates a virtuous cycle.

[0084] The two-row, one-strip layout ensures a suitable distance between the planting rows and the eaves of the photovoltaic panel 1, preventing the growth of shrubs 3 from obstructing the cleaning, inspection, and other maintenance work of the photovoltaic panel 1, and ensuring unobstructed access for operations. In addition, sand willow or straw sand barriers, as locally adapted materials, are flexible and wear-resistant, which can reduce the direct impact of wind and sand on the edges of the photovoltaic panel 1, reduce the risk of equipment damage, and ensure the safe operation of the photovoltaic field.

[0085] like Figure 6 , 7 As shown, in an optional embodiment of this utility model, the fifth windbreak and sand-blocking forest belt includes:

[0086] The second sand barrier 4 intersects perpendicularly with each other, and the second sand barrier 4 as a whole is a grid pattern;

[0087] Shrubs 3 are placed within the squares of the second sand barrier 4.

[0088] Specifically, the second sand barrier 4 is a sand willow sand barrier. The shrub 3 can be of the varieties of Haloxylon ammodendron and Caragana korshinskii, with different varieties of shrub 3 mixed and interspersed, with a planting density of 2m×2m.

[0089] In this embodiment, by constructing the windbreak and sand-blocking forest belt between the photovoltaic panel 1 and the operating road 5, wind and sand can be effectively intercepted, reducing the coverage of sand and dust on the surface of the photovoltaic panel 1 and its erosion of the equipment, thereby reducing power generation efficiency loss and equipment failure risk. At the same time, the forest belt can serve as an ecological barrier for the operating road 5, improving the safety of site operation and maintenance, and providing a solid guarantee for the coordinated development of photovoltaic power generation and desertification control.

[0090] The fifth windbreak and sand-fixing forest belt is set between the photovoltaic panel 1 and the working road 5. It uses a grid pattern of sand willows and mixed shrubs of Haloxylon ammodendron and Caragana korshinskii to closely fit the narrow spatial structure of the area. This layout can effectively utilize the limited space to build a windbreak and sand-fixing barrier, while avoiding obstruction to the passage of the working road 5 and the operation and maintenance of the photovoltaic panel 1, thus achieving a coordinated and unified approach between sand control measures and the functional layout of the site.

[0091] The intersecting grid of sand barriers can form a three-dimensional sand-blocking grid on the ground, effectively separating shifting sand, reducing wind speed, and preventing sand and dust from accumulating on the work road 5. The mixed planting of saxaul and tamarisk trees within the grids, through the dual effects of soil stabilization by the vegetation roots and physical sand blocking by the sand barriers, constructs a composite protection system of grid sand blocking and vegetation sand locking, which can significantly enhance the protection of the work road 5, reduce the risk of wind and sand burying the road, and ensure the long-term unobstructed access of the site's operation and maintenance channels.

[0092] The mixed planting of Haloxylon ammodendron and Caragana korshinskii utilizes their different ecological characteristics to complement each other, enhancing the resilience and sand-fixing stability of the vegetation community. Simultaneously, the planting density of 2m×2m ensures vegetation coverage while avoiding water competition caused by over-dense planting, adapting to the arid desert environment and improving vegetation survival rate and long-term sand-fixing effectiveness.

[0093] like Figure 8 As shown, in an optional embodiment of the present invention, the third windbreak and sand-blocking forest belt includes a first sand barrier 2 that intersects perpendicularly with each other, and the first sand barrier 2 is generally in the form of a mesh grid.

[0094] Specifically, the first sand barrier 2 is a sandbag sand barrier, the material of which is a biodegradable material, and the layout specification of the sandbag sand barrier is 2m×2m.

[0095] In this embodiment, by constructing the windbreak and sand-blocking forest belt under the photovoltaic panel 1, the accumulation of sand and dust at the bottom and around the photovoltaic panel 1 can be effectively reduced, thereby reducing the impact of sand and dust on the heat dissipation and power generation efficiency of the photovoltaic panel 1.

[0096] The third windbreak and sand-blocking forest belt is set under the photovoltaic panel 1, and uses biodegradable material sandbags to form a mesh grid that can closely fit the space under the photovoltaic panel 1. It can reduce the evaporation of moisture from the sand barrier by utilizing the shading effect of the photovoltaic panel 1, and avoid the sand barrier from adversely affecting the installation, heat dissipation and power generation efficiency of the photovoltaic panel 1, thus achieving an organic adaptation between the sand control measures and the microenvironment under the photovoltaic panel 1.

[0097] The intersecting grid of sandbags can form a three-dimensional sand-blocking structure under the photovoltaic panel 1, effectively separating the flowing sand, reducing wind speed, and preventing sand and dust from accumulating under the panel; the sandbags made of biodegradable materials can naturally degrade after fulfilling their sand-fixing mission.

[0098] This utility model divides different functional areas into different areas of the photovoltaic field (such as photovoltaic panels 1, working roads 5, and booster stations 6) based on their functions and location characteristics. Each area is equipped with appropriate sand barriers and vegetation, which changes the traditional practice of directly replicating desertification control models and makes desertification control measures more adaptable to photovoltaic fields.

[0099] Setting up windbreak and sand-blocking forest belts in different areas can effectively intercept external wind and sand, reduce the erosion of photovoltaic panels 1, operation roads 5 and substation 6 by wind and sand, reduce the problem of reduced power generation efficiency caused by sand and dust covering photovoltaic panels 1, ensure the long-term unobstructed operation and maintenance channels of the site, reduce the risk of equipment failure, and provide a guarantee for the safe and stable operation of the photovoltaic site.

[0100] By combining a grid-like sand barrier with shrubs arranged in different ways, a composite sand-fixing system of grid sand fixation and vegetation sand locking is formed, which effectively separates shifting sand, reduces wind speed, prevents sand dune movement, and significantly improves the stability of the sand-fixing structure.

[0101] The two-row, one-belt layout preserves space for natural vegetation restoration, promotes the natural recovery of local plant communities, and the mixed and interspersed arrangement of different shrub species enhances the resilience and ecological diversity of the vegetation community.

[0102] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
